Title: Process for the production of acetaldehyde from acetylene
Filed: 1920-03-24
Abstract: The acetylene used in the manufacture of acetaldehyde is purified, particularly from phosphoretted hydrogen; this may be effected by washing the gas with metal oxychlorides followed by a hydrochloric acid solution of mercuric chloride.ALSO:In the production of acetaldehyde by passing acetylene into aqueous acid solutions containing a mercury catalyst, the catalyst is prepared by mixing metallic mercury with a suitable oxidizing-agent, particularly ferric oxide, and adding water and acid; preferably sulphuric acid is used in amount equal to 30-35 per cent of the other ingredients.  The acetylene used should be purified, particularly from phosphoretted hydrogen; this may be effected by washing the gas with metal oxychlorides followed by a hydrochloric acid solution of mercuric chloride.  The reaction liquid is maintained at 70 to 83 DEG  C., the acetylene is passed in excess, and a mechanical agitator employed. Water is added at intervals to maintain the strength of the liquid, and the ferric oxide and sulphuric acid are also renewed at intervals. Specification 24153/14 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to preparing the catalyst from reduced mercury, or a mercury salt instead of metallic mercury, and to the use of other acids such as acetic acid or sulphoric acids in place of sulphuric acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 242,168. Marks, E. C. R., (Libbey-Owens Sheet Glass Co.). April 8, 1925. Drawing.-A method of producing sheet glass consists in supplying molten glass continuously to a container so that it overflows at opposite sides in shallow even streams which flow together below the container to form a single sheet. The container, as shown in end elevation in Fig. 1 and in cross-section in Fig. 3, consists of a wedge-shaped body 6, of fireclay, formed with a trough 22, and two supply-pots 7 which mav be formed in one with the body 6. The container is adjustably arranged at the end of a tank 2 from which it receives metal by two side conduits 3, the supply of metal being regulated by gates 4. The two streams of metal flow through the pots 7 into the trough 22, and the metal therein flows over the opposite edges and down the sides of the wedge 6 in two shallow even streams which unite below the wedge to, form a sheet 28. The sheet is drawn away by suitable drawing-apparatus 31 in an annealing chamber 30. The temperature of the metal is regulated by burners 25 in a heating-chamber 24, and by an electric heater 27 placed within the bodv of the wedge.
